  • Effects of 17β-estradiol on typical greenhouse gas emissions in aquatic anaerobic ecosystem

    Anaerobic microecosystems designed with different concentrations of 17β-estradiol (17β-E2) (0.0–10,000.0 ng/L) were simulated in this study. The influence of different concentrations of 17β-E2 on the emissions of typical greenhouse gases (CH4 and CO2) in simulated anaerobic microecosystems is analyzed to primarily explore the relationship between ...

  • Advances in flashpoint testing: economic impact

    Flashpoint testing is one of the oldest methods of the ASTM D02 Committee on Petroleum Products and Lubricants, which was formed in 1904. The most prevalent standards are ASTM D56 (Tag Method), D92 (Cleveland Method), and D93 (Pensky-Martens Method). These classical techniques, commonly referred to as open-cup and closedcup methods, share a common principle: A test flame is lowered into the ...

  • Detecting Gases: What You Can`t Smell Can Hurt You

    Walking through a drill-site area, a worker smells rotten eggs and stops tor a minute or two to assess where a gas leak might exist. Rubbing his itchv eves as he investigates further, he notices that he no longer smells the tell¬tale hydrogen sulphide odour. He does not realize that the gas has deadened his olfactory senses and unless he leaves the area within seconds, he could lose ...

  • Process analytics in gas-to-liquid (GTL) plants – Case Study

    NG, FT and GTL Natural Gas (NG) is a vital component of the world's supply of energy. It is one of the cleanest, safest, and most useful of all energy sources. NG is colorless, shapeless, and odorless in its pure form. It is combustible, and when burned it emits lower levels of potentially harmful byproducts into the air than other fuels. NG is a mixture of hydrocarbon gases. While it ...

  • Analysis of trace hydrocarbon impurities in 1,3-Butadiene using optimized RT-Alumina BOND/MAPD plot columns

    Abstract Identifying and quantifying trace impurities in 1,3-butadiene is critical in producing high quality synthetic rubber products. Standard analytical methods employ alumina PLOT columns which yield good resolution for low molecular weight hydrocarbons, but suffer from irreproducibility and poor sensitivity for polar hydrocarbons. In this study, Rt-Alumina BOND/MAPD PLOT columns were ...

  • Effects of mixing on chloramination process

    According to a recent study more than 90 percent of water treatment plants utilizing chloramination for distribution system residuals indicate a certain level of dissatisfaction toward the process performance. One factor that may lead to such dissatisfaction is the inadequacy of mixing when ammonia is added to chlorinated water. If mixing is not instantaneous and uniform, the actual chlorine to ...

  • Process analytics optimizes crude gas processing for the production of fine chemicals at Lonza – Case Study

    Fine chemicals are used as active ingredients or additives in the pharmaceutical and food & beverages industries, as well as in agriculture. The cracking of raw materials such as light virgin naphtha or liquefied gas results in intermediate products (ethylene, hydrogen, methane, CO2). At the end of the process chain, these can provide highly pure materials such as niacin (vitamin B3) or ...
